I did a check on my server to see what extensions are being used by clients and there only seems to-be 10 extensions in use by the most common imap clients.
Clients: Apple Mail, Thunderbird, Mobile Mail, Outlook and php imap client. Mark your client is missing but I'm sure you can add any missing extensions to the list :-)
Extensions: STARTTLS, AUTH=, LOGINDISABLED, UIDPLUS, LITERAL+, NAMESPACE, IDLE, ACL, UNSELECT and QUOTA.
I'm sure there are some more clients which use a few more extensions, but that still means ~16 extensions we (Isode) have implemented are not being used. Not a very good ratio. Yet, here we are planning on adding more.
